Q: Can I update via the Bluetooth app?
No. The D8 does not have a companion app. Updates require a USB cable and PC.

Q: My D8 is working fine. Should I update?
No. “If it ain’t broke, don’t fix it.”

Q: I can’t find any firmware file. What now?
Contact W-King support directly with your issue. They may send you a file if an update exists for your specific problem.

Q: Does the D8 support over-the-air (OTA) updates?
No.


Note: W-King does not have a universal updater. The exact method depends on the update file provided. Below is the most common procedure for their DSP-based speakers.

What you’ll need:

Typical steps:

⚠️ If the speaker becomes unresponsive after an update: Try a factory reset (press and hold Volume+ and Volume- simultaneously for 5-10 seconds). If that fails, contact support for recovery instructions.


  • Follow official instructions exactly: Use only firmware from the manufacturer’s official site or official app.
  • Avoid interrupting: Do not power off, disconnect, or close the updater during flashing.
  • Post-update check: Test basic functions (power, pairing, playback, buttons, charging, LED indicators) and any previously problematic behaviors.
  • If issues occur: Retry the update with recommended recovery steps, consult support, or return to the vendor.
